2017-02-06	iwlwifi: mvm: overwrite skb info later	Johannes Berg	1	-5/+15
	We don't really need clear the skb's status area nor store the dev_cmd into it until we really commit to the frame by handing it to the transport - defer those operations until just before we do that. This doesn't entirely fix the bug with frames not getting sent out after having been deferred due to DQA, because it doesn't restore the info->driver_data[0] place that was already set to zero (or another value) by the A-MSDU logic.
